Description

Technical Field

[0001] The invention relates to the field of plate processing fixtures, and in particular to a special-shaped plate processing fixture. Background Art

[0002] The stable plate clamp disclosed in the existing announcement number CN108723836A can place the plate that does not need to be processed flat on the base when in use, then rotate the rotating rod around the hinge to tightly attach the clamp to the top surface of the plate, and then tighten the screws one by one in the corresponding threaded holes on the clamp and the base, and tightly connect the base and the clamp to clamp the plate, so that the plate can be fixed and machined. The stable plate clamp can clamp and fix a flat workpiece and machine it, with a large clamping area, a high degree of tightening, and good clamping stability, ensuring the machining accuracy;

[0003] As in the above-mentioned patent, in addition to flat plates, there are also curved plates in actual use. Curved plates are different from conventional plates. During processing such as grinding and drilling, if the curved plates are directly spread on a conventional flat tabletop, it is easy to cause the plates to deform and be damaged. Therefore, it is necessary to set up a clamp platform that conforms to the curved plates. The bearing surface of such a clamp platform is a curved surface that fits the curved plate. When the curved plate is placed on it, all parts can be supported. The curved plate is clamped by a clamp, and then when the worker operates the equipment to perform drilling or grinding, all parts of the curved plate can be supported and will not be deformed. However, this type of clamp platform used for processing curved plates has the problem of being unable to be adjusted. Therefore, when the diameter of the curved plate changes, its curvature will also change accordingly. The non-adjustable curved clamp platform can only support curved plates of a single diameter, and has poor adaptability. Summary of the invention

[0026] By providing a plurality of supporting bars 3 and providing a spacing adjustment mechanism 5 to simultaneously adjust the spacing between the plurality of supporting bars 3 and the supporting sleeve 2, the plurality of supporting bars 3 can be made to support and place arc-shaped plates of various different diameters, thereby enabling the entire clamp to clamp arc-shaped plates of various different diameters, thereby greatly improving the adaptability of the clamp. During the production and manufacturing process, the enterprise does not need to purchase arc-shaped plate clamp platforms of various different specifications, thereby greatly saving production and manufacturing costs.

[0027] Sliding rods 6 are symmetrically fixed at both ends of the bearing bar 3, and a fixing sleeve 7 is provided on the outer sliding sleeve of the sliding rod 6. The fixing sleeve 7 is fixed to the outer wall of the bearing sleeve 2 at one end away from the bearing bar 3; the bearing bar 3 can slide along the sliding rod 6 in the fixing sleeve 7, thereby adjusting the distance with the bearing sleeve 2.

[0028] The clamping mechanism 4 includes an electric push rod 41, wherein the electric push rod 41 is fixed to the end of one of the supporting bars 3, a push plate 42 is installed at the protruding end of the electric push rod 41, and a baffle 43 is also fixed to the end of the supporting bar 3 to which the electric push rod 41 is fixed, which is away from the electric push rod 41, and the baffle 43 is opposite to the push plate 42; the baffle 43 is opposite to the push plate 42, and by driving the electric push rod 41 to extend, the push plate 42 and the baffle 43 jointly form a clamping force for clamping the arc-shaped plate.

[0029] The clamping mechanism 4 is installed on a load-bearing bar 3 located in the middle of the plurality of load-bearing bars 3. Such a design can maintain central clamping, ensure the balance of the clamping force, and make the plate more stable during processing.

[0030] An adjusting sleeve 421 is fixed to one end of the push plate 42 close to the electric push rod 41, and the adjusting sleeve 421 is slidably sleeved on the protruding end of the electric push rod 41. A limiting mechanism 422 for limiting the position of the adjusting sleeve 421 on the protruding end of the electric push rod 41 is installed on the adjusting sleeve 421; the limiting mechanism 422 includes a side sleeve 4221 fixed to the outer wall of the adjusting sleeve 421, and a latch 4222 is slidably plugged into the inner wall of the side sleeve 4221, and the latch 4222 is slidably connected to the side wall of the adjusting sleeve 421 through a sliding hole. The end of the pin 4222 passes through the side wall of the adjusting sleeve 421 and extends to the inner side of the adjusting sleeve 421. A plurality of slots 4223 are evenly spaced on the outer wall of the protruding end of the electric push rod 41. The latch 4222 cooperates with the slots 4223.

[0031] When clamping arc-shaped plates of different lengths, the handle 4225 is pulled to pull the latch 4222 out of the slot 4223, and then the push plate 42 is moved to make the adjustment sleeve 421 slide on the extended end of the electric push rod 41 until it is adjusted to the right position, and then the handle 4225 is released, and the latch 4222 is pushed into the slot 4223 under the action of the elastic force of the spring 4224, thereby completing the limiting work;

[0032] By installing a push plate 42 adjustably at the extended end of the electric push rod 41, it is possible to clamp arc-shaped plates of various lengths, further improving the adaptability of the entire clamp;

After the adjustment is completed, the rotating mechanism 56 stops working, and the position of the bearing bar 3 is limited. Then, the arc-shaped plate is laid on the outside of the multiple bearing bars 3, and the arc-shaped plate is supported by the multiple bearing bars 3;

[0035] The arc-shaped plate is then clamped by the clamping mechanism 4, and people can then perform processing work such as drilling or grinding on the plate.

[0036] For example 2, please refer to Figure 6 This embodiment provides a further technical solution based on the first embodiment. The rotating mechanism 56 includes a worm 561 rotatably mounted on the top of the base plate 1 through a bearing. A worm wheel 562 is fixed on the outer wall of the connecting ring 51.
